[frequency and significance of parasitic infections in refugees from vietnam (author's transl)].in the course of the medical care which is provided for the refugees from southeast asia 100 persons were tested for intestinal parasites (helminths and protozoa). in addition serum samples were obtained from 72 of these and tested in several tests (cft, fat, iha and sft) using antigens of entamoeba histolytica, leishmania donovani, toxoplasma gondii, schistosoma spp., fasciola hepatica, echinococcus spp., trichinella spiralis and litomosoides carinii. in 49 persons infections with one, two or ...19807395245
in vitro and in vivo activities of a triterpenoid saponin extract (px-6518) from the plant maesa balansae against visceral leishmania species.the in vitro and in vivo activities of a mixture of six oleane triterpene saponins, recovered from the methanolic extract of the leaves of the vietnamese plant maesa balansae (px-6518), were evaluated against drug-sensitive visceral leishmania strains. the in vitro 50% inhibitory concentration (ic(50)) against intracellular leishmania infantum amastigotes was 0.04 micro g/ml. the cytotoxic concentrations causing 50% cell death (cc(50)s) were about 1 micro g/ml in murine macrophage host cells and ...200414693530
anti-protozoal activities of cembrane-type diterpenes from vietnamese soft corals.based on our previous finding that certain cembranoid diterpenes possess selective toxicity against protozoan pathogens of tropical diseases such as trypanosoma and plasmodium, we have subjected a series of 34 cembranes isolated from soft corals living in the vietnamese sea to an in vitro screening for anti-protozoal activity against trypanosoma brucei rhodesiense (tbr), t. cruzi (tc), leishmania donovani (ld), and plasmodium falciparum (pf). twelve of the tested compounds displayed significant ...201526184133
